However, many emerging market and developing economies continue to struggle with the covid-19 pandemic and its aftermath.
Despite the recovery, global output will be about 2% below pre-pandemic projections by the end of this year.
Among low-income economies, the effects of the pandemic have reversed poverty reduction gains and aggravated insecurity and other long-standing challenges.
"While there are welcome signs of global recovery, the pandemic continues to inflict poverty and inequality on people in developing countries around the world," said World Bank Group President David Malpass in a press release on Tuesday.
"Globally coordinated efforts are essential to accelerate vaccine distribution and debt relief, particularly for low-income countries. As the health crisis eases, policymakers will need to address the pandemic’s lasting effects and take steps to spur green, resilient, and inclusive growth while safeguarding macroeconomic stability," he stated.
Among major economies, US growth is projected to reach 6.8% this year, reflecting large-scale fiscal support and the easing of pandemic restrictions.
Among emerging markets and developing economies, China is anticipated to rebound to 8.5% this year, reflecting the release of pent-up demand.
Emerging market and developing economies as a group are forecast to expand 6% this year, supported by higher demand and elevated commodity prices.
However, the recovery in many countries is being held back by a resurgence of covid-19 cases and lagging vaccination progress, as well as the withdrawal of policy support in some instances.
Excluding China, the rebound in this group of countries is anticipated to be a more modest 4.4%.
The recovery among emerging market and developing economies is forecast to moderate to 4.7% in 2022.
Even so, gains in this group of economies are not sufficient to recoup losses experienced during the 2020 recession.
Moreover, output in 2022 is expected to be 4.1% below pre-pandemic projections.
Growth in low-income economies this year is anticipated to be the slowest in the past 20 years other than 2020, partly reflecting the very slow pace of vaccination.
Low-income economies are forecast to expand by 2.9% in 2021 before picking up to 4.7% in 2022.
The group’s output level in 2022 is projected to be 4.9% lower than pre-pandemic projections.
